1. TOWARDS A REVIEW OF THE DECAPOD CRUSTACEA FROM THE REMOTE OCEANIC ARCHIPELAGO OF TRINDADE AND MARTIN VAZ, SOUTH ATLANTIC OCEAN: NEW RECORDS AND NOTES ON ECOLOGY AND ZOOGEOGRAPHY
RESUMO O grande isolamento geográfico do jovem arquipélago vulcânico Trindade e Martin Vaz (TMV) suscita questionamentos sobre a origem e os níveis de endemismo de sua fauna. Entretanto, a abordagem destas questões requer o conhecimento abrangente da composição taxonômica da fauna bentônica marinha de TMV. Com o intuito de documentar a biodiversidad

2. Poluentes orgânicos persistentes na biota marinha do Arquipélago de São Pedro e São Paulo / Persistents Organic Pollutants in marine biota of the São Pedro e São Paulo Archipelago
Some oceanic islands, such as São Pedro e São Paulo Archipelago may be considered remote areas and preserved due to its distance from the mainland. However, these areas are not exempt from the influence of anthropogenic agents from coastal regions, such as persistent organic pollutants (POPs). This proposal aimed to determine the occurrence and distributio

3. Influência da composição de substrato do recife na atividade e distribuição de peixes zoobentívoros no arquipélago de Fernando de Noronha, Pernambuco / The influence of substratum composition on the activity and distribution of benthic carnivorous reef fishes of the Fernando de Noronha Archipelago
Reefs provide shelter and food for several fish species and, thus, there may be a correlation between the abundance and behaviour of fishes and the reef bottom composition-Physical factors, such as water movement and depth, may also have a profound impact in species distribuiton and activity on reefs. Here, the possible relationship between the distribution

4. O termo de ajustamento de conduta como instrumento mediador de conflitos de competÃncias administrativas ambientais: o caso de Fernando de Noronha
This search analyze the applicability of the legal instrument TAC - Term Adjustment of Conduct in the island space to mediate the conflict of administrative competence between the federal and state government to the environmental management. The research was developed in the archipelago of Fernando de Noronha. This geographical area, since the Portuguese col

5. Composição, densidade e variação espaço-temporal de larvas de decápodes e estomatópodes do arquipélago de São Pedro e São Paulo, Brasil / Composition, density and spatial-temporal distribution of decapods and stomatopods larvas of the Saint Pauls archipelago, Brazil
The present study describes the composition, density and the temporal, diel and spatial distribution of decapod and stomatopod larvae present in surface waters of Saint Pauls Rocks. The expeditions to the archipelago were carried out in April, August and November of 2003, March of 2004 and May of 2005. Surface plankton samples were collected during the morni

6. Degradação de naftaleno, fenantreno e benzo(a)pireno em solos e sedimentos de ambientes costeiros, oceânicos e antárticos / Degradation of naphthalene, phenanthrene e benzo(a)pyrene in soil and sediments of coastal, oceanic and Antarctic environments
Petroleum is the main source of fuel, and the operations of exploration, transportation, refining and distribution are potential sources of environmental pollution. In contaminated environments, the degradation of PAHs (Polycyclic Aromatic Hydrocarbons) depends on climatic factors, soil and microbial population. This study aimed to assess the potential for d

7. Micobiota fitopatogênica associada à planta invasora Tibouchina herbacea / Mycobiota of the invasive weed Tibouchina herbacea
Weed plant invasions, in natural as well as in anthropic modified environments, results in significant economical losses or ecosystem disequilibrium. Some ecosystems are more susceptible than others to biological invasions, once they have disharmonic fauna and flora (with empty ecological niches or niches occupied by low adapted species to the ecological fun

8. Caracterização e classificação de solos da Ilha de Fernando de Noronha (PE)
In the main island of Fernando de Noronha Archipelago, the dry tropical climate with oceanic influence and the recent parent material of volcanic origin, are responsible for the small weathering of soils with high scientific importance for the development of the Brazilian System of Soil Classification (SiBCS). Seven representative soil profiles, involving tw

9. Idade, crescimento e uso do habitat das espÃcies Stegastes rocasensis, no Atol das Rocas e Stegastes sanctipauli, no ArquipÃlago de SÃo Pedro e SÃo Paulo
Although the importance of coral reef environments, it is known by scientists all around the world that this ecossistem is actually under potencial impacts and declining. A vital part of coral reefs ecossistems is composed by coral reef fishes. It is estimated that 30-40% of marine fishes can be found in coral reefs. The Pomacentridae family has an important

10. Hidrology or the banks and oceanic islands of the north-east Brazil. A contribuition to the program revizee / Hidrologia dos bancos e ilhas oceânicas do nordeste brasileiro. Uma contribuição ao Programa Revize.
This work has as objectives to supply data on the temperature, salinity, dissolved oxygen, pH and nutrients (nitrite, nitrate, phosphate and silicate), of the areas of the banks and oceanic islands of the Zone Economic Exclusive of North-East Brazil, to describe seasonal and the spatial variations of these parameters and to systematize the obtained data, thr

11. Giant tortoises are not so slow: Rapid diversification and biogeographic consensus in the Galápagos
Isolated oceanic archipelagos have played a major role in the development of evolutionary theory by offering a unique setting for studying spatial and temporal patterns of biological diversification. However, the evolutionary events that cause associations between genetic variation and geography in archipelago radiations are largely unknown. This finding is

12. Chloroplast DNA evidence of colonization, adaptive radiation, and hybridization in the evolution of the Macaronesian flora.
Most evolutionary studies of oceanic islands have focused on the Pacific Ocean. There are very few examples from the Atlantic archipelagos, especially Macaronesia, despite their unusual combination of features, including a close proximity to the continent, a broad range of geological ages, and a biota linked to a source area that existed in the Mediterranean
